Got a strange issue where Contact Form 7 isn't working on the homepage of this sitebut it does work here on the Contact Us page of the same site. I checked the settings of the two forms and in the Mail tab, I've got my email address in the To: field, [your-email] in the From:, a regular subject line in the Subject: field and Reply-To: [your-email] in the Additional Headers:.
This is all the code I've got in the Form window:
<p>[text* your-name "Name"]</p>
<p>[text* your-company "Company"]</p>
<p>[email* your-email "Email"]</p>
<p>[submit "Join Us"]</p>
So why wouldn't this be working?
